I found new info on the Johnsons that says they may have come from Montgomery Co.,MD. So I'll put this query thru again. Thanks. Hello List, I just joined this list a couple of days ago. I am hoping to learn some info on Mary Johnson wife of Capt. Judson Coolidge. They married c Feb 1760. They resided in Upper Marlboro, Prince George's Co., Maryland. The info I have on Mary Johnson says she is the daughter of Peter Johnson. They may have come from Montgomery Co., Maryland. I would like to know if there is anyone out there researching this family? Does Mary Johnson Coolidge look familiar to anyone? Thank you for your help. Shirley Middleton-Moller
